Member Function Documentation

cycleEnd()

llvm::Error llvm::mca::EntryStage::cycleEnd ( )

overridevirtual

Called once at the end of each cycle.

Reimplemented from llvm::mca::Stage.

Definition at line 58 of file EntryStage.cpp.

References llvm::find_if(), I, and llvm::make_range().

cycleStart()

llvm::Error llvm::mca::EntryStage::cycleStart ( )

overridevirtual

Called once at the start of each cycle.

This can be used as a setup phase to prepare for the executions during the cycle.

execute()

llvm::Error llvm::mca::EntryStage::execute ( InstRef &  IR )

overridevirtual

The primary action that this stage performs on instruction IR.

Implements llvm::mca::Stage.

Definition at line 41 of file EntryStage.cpp.

References assert(), llvm::mca::InstRef::invalidate(), and llvm::mca::Stage::moveToTheNextStage().

hasWorkToComplete()

bool llvm::mca::EntryStage::hasWorkToComplete ( ) const

overridevirtual

Returns true if some instructions are still executing this stage.

Implements llvm::mca::Stage.

Definition at line 22 of file EntryStage.cpp.

Referenced by EntryStage().

isAvailable()

bool llvm::mca::EntryStage::isAvailable ( const InstRef &  IR ) const

overridevirtual

Returns true if it can execute IR during this cycle.

Reimplemented from llvm::mca::Stage.

Definition at line 24 of file EntryStage.cpp.

References assert(), llvm::mca::Stage::checkNextStage(), llvm::mca::SourceMgr::hasNext(), llvm::mca::SourceMgr::peekNext(), and llvm::mca::SourceMgr::updateNext().
